Research projects :
Circadian Rhythms, the Efficacy and Side Effects of Chemotherapy
Due to circadian rhythms, the efficacy and side effects of chemotherapy change throughout the day. Chemotherapy, in turn, alters circadian rhythm. This creates a closed-loop requiring control. While circadian rhythms can be monitored using blood/salivary/urine hormone tests, such tests are not practical at home and do not provide continuous real-time monitoring. Therefore, the main aim is to combine artificial intelligence (machine learning and deep learning) and signal processing with commercial sensors embedded in smartwatches or clothes that measure physiological and behavioural attributes (features/variables) to offer unprecedented and as yet unexplored opportunities to monitor circadian rhythms in real time.
Health Technology Assessment (HTA) of Medical Devices (MDs) in low and middle-income countries (LMIC)
The project is focused on Health Technology Assessment (HTA) of Medical Devices (MDs) in low and middle-income countries (LMIC), supporting the development of guidelines on HTA for LMICs.
In fact, the majority of medical devices are designed for Europe and USA, where there are clear standards and harmonized regulations on minimum requirements for design and maintenance of medical-location plants (i.e., electric, air and water plants in surgical theatres, ambulatory etc.). These standards and regulations allow transferring medical devices among hospitals/countries maintaining the same level of safety and efficacy. In many LMICs, those minimum requirements are not homogeneously guaranteed (and will not in the short term) and there is little evidence on how this affects patient safety, medical device efficacy and therefore the HTA of MDs. In order to measure the effects in safety and efficacy when MDs are operationalised in LMICs, and how this impacts on their HTA, field analyses are performed in sub-Saharan Africa (e.g., Burkina Faso, Benin, Mozambique or Nigeria). Plants and MDs in surgical theatres in sub-Saharan Africa are being analysed to quantify how far they are from meeting EU/USA standard and how this may affect medical device safety, efficacy and assessment.
Biomedical Signal Processing and Modelling for adverse Events prediction
Shifting healthcare monitoring techniques from the laboratory into real-life scenarios is very challenging. The current shift towards the use of advanced sensors into everyday objects (e.g., smart watch) is strongly increasing the need of reliable methods and tools to analyse healthcare information acquired into real-life settings for wellbeing applications.
Some of the main challenges and limitations arising from the application of traditional methods of signal processing, mainly developed to be used in laboratory settings were identified, and I proposed novel solutions to allow real-life monitoring of vital signs. In other words, my Ph.D. in biomedical engineering has been devoted to the translation of advanced methodologies and techniques from laboratory into real-life settings for prediction of adverse healthcare events.
My PhD activities resulted in 5 peer-reviewed published papers in first quartile journals. Moreover, 13 full-conference-papers were presented at international conferences. The research I have conducted over the years is highly interdisciplinary, combining engineering with knowledge from several medical specializations, computer science and business.
